Gives Claude native control over Windows 10/11 through the Model Context Protocol. You get file operations (read, write, delete, search), clipboard access, screenshots (full screen, window, or region), process management with a protected blocklist, and power controls. The server runs as a system tray app listening on localhost or LAN, exposing everything over HTTP with UTF-8 support for non-ASCII paths. Built in C++17 with no runtime dependencies. Useful when you need an AI assistant to actually manipulate files, grab screen content, or manage running processes on a Windows machine instead of just talking about it. Auto-updates from GitHub releases and includes audit logging for every operation.
